San Diego  A driver who hit and killed a nanny pushing a baby in a stroller in Torrey Highlands last month has been charged with misdemeanor vehicular manslaughter, the City Attorney’s Office said Monday.

Christine Padilla, 35, is also facing one count of failure to yield to a pedestrian within a crosswalk and one count of failure to stop at a red light, said Gina Coburn, a spokeswoman for the city attorney.

Mendez died at the scene and the 13-month-old was hospitalized with critical injuries.

The San Diego Police Department forwarded the case to the City Attorney’s Office on Feb. 12. The investigation found that Padilla was neither speeding nor using her cellphone when the crash occurred, police said. She had just had a baby the day before, police said.

Mendez, described by friends as a loving caretaker, was the single mother of a 13-year-old son and 15-year-old daughter. She had been working for the baby’s family since September. A memorial fund benefiting her family was set up at Wells Fargo Bank.

Padilla, who was not injured in the collision, is scheduled to be arraigned at 12:30 p.m. on March 18, Coburn said. If convicted on the manslaughter charge, she could face a maximum of one year in jail, the spokeswoman said.

According to the Department of Motor Vehicles, Padilla had no previous violations on her driving record.
